Reflective Index used to apply to CRT monitors and was a gauge of how much reflected light came off a monitor. A reflective index of < 15% was good. Today's TFT LCD monitors typically have a reflective index of less than 1%, especially those that are backlit, so the term has gone out of use now, and is no longer relevant.

Do impurities raise or lower the refractive index of a substance?
Impurities can cause a significant change in the reflective index of a liquid. Impurities totally affect the results of the experiment. It changes the reflective index and affect the concentration of the solution.
Is there any way to get scope with anti-reflective device and mildots for 200?
Yes, HOWEVER- merely having mildots and an anti-reflective does NOT mean that it will be a high quality scope. You will get what you pay for.

What is an objects ability to reflect sunlight called?
Reflectivity, index of refraction and optical density are all ways to measure reflective light.
Does Foods containing high amounts of refined sugars have a low glycemic index?
No. Foods with high refined sugar amounts have a high glycemic index.
What is the index?
in a book there is a section that tells you where things are.
Why optically dense mediums have high refractive index?
A transparent medium is sometimes said to have a high optical density (or to be relatively dense) if it has a high refractive index.

Define penetration index and show how it is related to temperature susceptibility?
high penetration index shows low temperature susceptibility, low penetration index shows high temperature suspectibility.
What surface has a low albedo?
The color black generally has the lowest albedo, or reflectivity.
What is the difference between high index and polycarbonate lenses?
High-index lenses are an alternative choice to standard, plastic eyeglass lenses. Although high-index lenses are more expensive than plastic lenses, they can reduce the thickness and weight of an eyeglass lens, particularly for individuals with a strong prescription. High-index lenses are able to bend light to a stronger degree than a lens with a lower index, therefore the higher the index of the lens the less material needed to achieve a given prescription. High index lenses are categorized according to how strongly they bend light. The higher the index, 1.53 to 1.74 for high-index lenses, the better the lens is at bending light. High index lenses are 20 percent to 65 percent thinner than standard plastic lenses. In general, the stronger the prescription, the greater the difference in thickness between standard plastic and high-index plastic. A reduction in lens thickness and weight will occur in high-index lenses for prescriptions stronger than +2.00 or -2.50. Weaker prescriptions are not thinner than standard lenses when made with high-index materials. Polycarbonate lenses offer the same aesthetic benefits as high-index lenses, but polycarbonate lenses scratch easier, are difficult to coat or tint and are more likely to create distortions in colors and vision.
